Today, environmental problems are shouted large, and something that the energy of nature can be effectively used even if it is low efficiency like the wind mill is reviewed. The jet pump is reviewed from the advantage such as being able to use the energy of nature effectively though is comparatively low efficiency. Therefore, this study did the study concerning the hydraulic transportation of the solid particle using the characteristic of the water type jet pump. The performance of the water type jet pump was investigated by changing nozzle to throat ratio from 0.27 to 0.67 and the driving pressure from 0.15 to 0.50MPa. Afterwards, the influence on the performance of the jet pump when the particle was transported in the maximum concentration was examined.
